Question

Differentiate function
R(x)= (square root of 10)/ x^7

Answer 1

i got square root of 10/ 7x^6 but it doesn't seem right

Answer 2

use 10^1'2 * x^-7

Answer 3

\[\frac{-7\sqrt{10}}{x^8}\]

Answer 4

don't let the
\[\sqrt{10}\] fool you. it is just a constant. like 3

Answer 5

i dont undesrstand how you got -7 on numerator

Answer 6

\[\frac{d}{dx}\frac{1}{x^7}=\frac{-7}{x^8}\]

Answer 7

if you like
\[\frac{1}{x^7}=x^{-7}\] so
\[\frac{d}{dx}x^{-7}=-7x^{-8}=\frac{-7}{x^8}\]

Answer 8

and the square root of ten just sits there. it is a number
